MTX-4 Intermediate Gear 23T Hardern Aluminium MTX4-0823 by 3Racing  [MTX4-0823]

23T Hardern Aluminium Gear for MTX-4 Gearbox

This aluminium second gear is a direct replacement made for the Mugen MTX-4 buggy drivetrain. Produced from Hardern aluminium, the 23-tooth part acts as the intermediate gear and is suited to scale and performance rebuilds that match MTX-4 geometry.

Function and compatibility: the item meshes with MTX-4 gearbox internals and cooperates with the vehicle's spur and pinion arrangement to establish final drive ratios. It is not designed as a universal alternative for different transmissions.

Fitting notes: when changing the second gear check associated bearings and shafts for wear, set correct gear mesh and backlash, and re-align the pinion after installation. Maintain original mounting direction and torque fasteners per guidance to avoid gear or case distortion.

Tuning use: swapping in this 23T second gear provides small ratio steps and works alongside alternative pinion or spur sizes to fine-tune response versus top speed. As an aluminium component expect different heat and wear characteristics compared with steel or nylon and verify mesh during test sessions.
